Grand Courier Eurasian Chess


GCE-Chess is my second (and final?) extension of Eurasian Chess by adding pieces from the Courier/Courier-spiel branch of the CV family. It retains all the piece types from Courier Eurasian Chess and then adds an orthogonal equivalent of the Elephant (the Warmachine), as well as a Guard and Champion. It also returns to a square board (12x12) rather than rectangular (14x10).

Initial Array


Notes on the board

  • To allow for the increased number of pieces from 16 in FIDE chess to 36 in GCE-chess the board increases to 144 squares.
  • The board density (piece/cell ratio) at commencement is thus maintained at the FIDE 50%.
  • In keeping with the Asian influence a river separates the board between the 6th and 7th ranks.
  • There is however no royal palace to restrict the King and his court. The King however is not permitted to cross the river; a restriction that also applies to the Fool, Elephant, and Warmachine.
  • Kings are also not allowed to occupy the same orthogonal or diagonal if there are no intervening pieces between them.

Notes on Piece Relationships

  • There are 15 piece-types.
  • The step-riders move linearly restricted only by other pieces and the edges of the board. They come in two families -
    • Sliders - which may capture the first enemy piece in their path.
    • Screeners - which move as sliders when not capturing, but must leap over one and only one piece (the screen) when capturing.
  • The non-riders make a single step or a hop (a double step unhindered by any piece occupying the first step.
    • The bi-directional step-hop piece is the Champion which combines the uni-directional moves of the Elephant and Warmachine).
    • The Champion's movement may also be seen as a combination of a step (King or Fool) with a hop in the same direction (Guard).
    • Where the hop changes direction (Horse) from that of the step (orthogonal-to-diagonal) the combination piece is the Sage.
